Understanding USB-C Power Delivery
USB-C Power Delivery (PD) is the universal charging standard. PD 3.1 supports up to 240W, but most phones need 20-65W and laptops need 65-100W. Buying a charger with more wattage than you need is safe - devices only draw what they require.
Key Specs to Check
- Wattage: Match your device's maximum charging speed. A 65W charger handles phones, tablets, and most ultrabooks.
- Ports: Multi-port chargers split wattage. A 100W dual-port charger might deliver 65W+35W or 50W+50W depending on the model.
- PPS Support: Programmable Power Supply enables Samsung Super Fast Charging and other proprietary fast-charge protocols.
- GaN Technology: Gallium Nitride chargers are smaller and more efficient than silicon-based chargers.
Top Picks by Use Case
Best single-port (phone): Anker 711 at 30W, $18. Compact and supports PPS for Samsung. Best multi-device: UGREEN Nexode 100W at $40, with 4 ports and smart power distribution. Best for travel: Anker Prime 67W at $35, folds flat and charges a MacBook Air at full speed.
Safety Matters
Avoid unbranded chargers from marketplace sellers. Legitimate chargers have UL/CE/FCC certifications, over-current protection, and temperature monitoring. A bad charger can damage your device's charging circuit or, in extreme cases, cause a fire.
